A fuel cell includes an electrolyte electrode assembly including a cathode, and an anode, and an electrolyte interposed between the cathode and the anode. The anode is made of porous material of Ni, for example. A dense layer is formed integrally on an outer circumferential surface of the anode as a protective layer by densifying process. The dense layer prevents an exhaust gas from flowing into the anode. The dense layer is formed by heating an outer circumferential region of the anode by a laser or the like. |
